```Single Riveting; Size of Rivets.

407

In a Single-riveted Lap Joint, as n Fig. 356, shear
strength of one rivet = tensile strength of plate between two
rivets,                                v ^

which is our general formula.    But the rivet (up to i" plates
bears a definite proportion to the plate thickness, thus :
d = 1*2 *J~i before riveting
d^ = i '3 Jt after riveting,   and t = *6 /x2

Also steel plates and rivets are the usual practice, where fs = 5 and
/t = 6. Putting these in the formula, we have

5 x 22 x d^         . „     ..         2

/.    pitch = i'09 + ^

which shews that the space between rivets is a constant quantity for
all plates up to i" thick. Also lap = 3 times d. (See Appendices I.
and Iff., pp. 760 and 920.)
